This is One set ZYX Ultimate Dynamic 0.15mV Low Output MC Cartridge , made in Japan by ZYX. TB2, ZN Premounted with 18K Terminal Pine.Condition: Brand new in box, not used beforeZYX ULTIMATE AIRYWorld First C-1000 Carbon Cantilever in Moving Coil Cartridge The ZYX Ultimate series (100, Airy, 4D, OMEGA and DYNAMIC) use a carbon cantilever for the very first time in a moving coil cartridge. The carbon rod is made from 1000 pieces of composite carbon fiber, hence the name C-1000 carbon cantilever. This composite carbon fiber is more rigid than aluminum, iron and titanium. In addition, its specific gravity is just half that of boron. Therefore we can be sure that the C-1000 carbon cantilever is the ultimate and ideal cantilever material for analogue record playback. The carbon cantilever gives the widest frequency range and a superior tracking performance. A further major benefit is that the mechanical sound signal picked up at the stylus can travel through to the coil in a straight and direct fashion by way of the 1000 pieces of mechanical carbon lines. This ensures that reflected, repeated or modulated mechanical sound signals are completely absent. The overall result is that you will enjoy some of the finest, most natural, most dynamic and true to source sound available. Double Structure Body By combining non-metallic materials in the construction of the body, the resonances occurring on the body’s surface are excluded from influencing the generator system. An additional advantage is that this method of construction is both light and rigid. High speed reproduction engine (magnetic circuit) This circuit is specially processed to null magnetic resistance within magnetic gap, and enables high speed power generation against signals over the entire bandwidth uniformly without time delay. Micro-Ridge Stylus The stylus used in the Ultimate series has the edges of the diamond shank set parallel to the sides of the cantilever. Using this type of stylus, the hardest axis of the crystal is aligned to act as the contact point with the record groove. This gives stable and smooth tracing and produces a very refined sound, with the additional benefit of giving the stylus an extended life of approximately 2000 hours. The stylus is of the Micro-ridge type, which was originally developed in Japan and offers the highest performance. The contact radius is always 3μm by the ridge made with 6μm thickness.
